چکیده
OBJECTIVE We measured serum NT-proBNP levels in 2 groups of young patients (0-36 months) with congestive heart failure (CHF) secondary to congenital heart malformations (CHM). METHODS The first group included 23 patients prior to surgery for heart malformations. The second group included 12 patients with CHM within 24 hours post-operation. NT-proBNP levels were measured by an enzyme-linked immunosorbent immunoassay (ELISA) using the Chem Well 2910 (Awareness Technology Inc.) automated analyzer. RESULTS NT-proBNP values were 4 times higher in patients with unoperated CHM compared to healthy controls (P < 0.001), and 12 times higher in patients with CHM 24 hours after surgery compared to controls (P = 0.0001). CONCLUSIONS These results demonstrated significant changes in NT-proBNP concentrations before and after surgery to correct congenital heart malformations.

Background: NT-proBNP is a marker that is released from ventricles in response to pressure and volume overload. Raised plasma level of NT-proBNP is seen in ventricular dysfunction, ventricular muscular mass reduction or ventricular ischemia. Anthracyclines are widely used in treatment of pediatric cancer but their use is associated with cardiotoxicity which increases mortality and morbidity. We...
